Chapter 5 Map Information Operations

The default header file, stored as /u[sr]/ltp/config/header, contains
information used for all newly created maps.  Some of the parameters in the
header file affect the processing environment, while others provide valuable
data which can be integrated into a file header for some of the export
formats.  The default_head command allows the user to update and/or display the
default header file.

default_head

    Updates/displays the default header file.

         decrement x y

    This command displays and/or modifies the default header file.  Only one
    item = string pair may accompany each default_head command.  The -p option
    prints the default header file to the default primary printer.
